OK, now that vertical timeline is merged into master, this is worth some consideration for future versions. What all should be highlighted in the timeline?
- gaps, periods of long inactivity?
- super highly liked posts?
- periods of crazy intense rapid post activity?
- famous people posts (blizzard employees?)
- moderator posts?
- topic splits or merges?
- Friday the 13th?
I dunno, 
brainstorm!
